Well,
Sexymama and I finally did the anal thing after some trepidation on both our parts and you know what? We both liked it.
We washed well, then cleaned her out with several bulbs of water, then we spent a long time playing, during which time I penetrated her rear with some of our smaller toys while masturbating her.
Then, I told her I wanted to fuck her ass and to my surprise, she said, "yes".
More lube and I was in!
I took it slow since I wasn't sure how she was feeling about it, but to my surprise she said she was enjoying it! Next thing I know, we're going at it hammer and tongs!!
Anyway, it was a great Father's day present and one I think we'll repeat...
